Existing file D:\JavaProject\mybatis_generator\generator\src\main\java\com\example\pojo\User.java was overwritten

根据提供的引用内容,可以看出这是在使用MyBatis Generator插件生成Java代码时出现的问题。当插件运行时,如果已经存在同名的Java文件,插件会覆盖原有的文件并生成新的文件。因此,如果出现类似的提示“Existing file xxx was overwritten”,说明插件已经成功地生成了新的Java文件并覆盖了原有的文件。
如果您不希望插件覆盖原有的文件,可以在插件的配置中设置overwrite为false,这样插件就不会覆盖原有的文件了。

no main manifest attribute, in mybatis-generator-core-2.3.0.jar
The error message "no main manifest attribute" typically occurs when you try to execute a JAR file that doesn't have a proper entry point defined in its manifest. In the case of the `mybatis-generator-core-2.3.0.jar`, it seems that the JAR file is meant to be used as a library and not as a standalone executable.
To resolve this issue, you need to use the `mybatis-generator-core-2.3.0.jar` as a dependency in your project rather than trying to execute it directly. Make sure to include it in your project's build path or add it as a dependency in your build tool configuration (e.g., Maven or Gradle).
If you are using Maven, you can add the following dependency to your `pom.xml` file:
```xml
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>2.3.0</version>
</dependency>
```
If you are using Gradle, you can add the following dependency to your `build.gradle` file:
```groovy
dependencies {
implementation 'org.mybatis.generator:mybatis-generator-core:2.3.0'
}
```
Remember to replace any existing conflicting dependencies with the appropriate version of `mybatis-generator-core`.
Once you have added the dependency correctly, you should be able to use the functionality provided by `mybatis-generator-core` in your project without encountering the "no main manifest attribute" error.
Cause: java.sql.SQLSyntaxErrorException: Unknown column 'orderbasetable_id' in 'field list'
This error occurs when a SQL query is trying to reference a column that does not exist in the table being queried. In this case, the column 'orderbasetable_id' is not present in the table being queried.
To fix this error, you need to check the SQL query and make sure that the column 'orderbasetable_id' exists in the table being queried. If the column does not exist, you may need to add it to the table or modify the query to reference an existing column.
